These specimens have pistillate flowers barely developed, and yet the leaves 

 are f inch long, which witli the young shoots are pubescent. In this pubescence 

 and the simultaneous appearance of flowers and loaves this western form seems 

 distinct from the eastern. 



EUPHORBIACE^. 



Euphorbia strictior ITolzinger n. sp. An erect perennial herb, from a thick deep root : 

 diffusely branched from the base, 15 to 25 inches high, glabrous except the inflo- 

 rescence; branches simple to the inflorescence, straight and rigid, grooved; 

 leaves alternate, 1 to 2| inches long, 1 line or less wide, generally more than 

 twice the length of the internodes, becoming relatively shorter toward the in- 

 florescence, sessile by a tapering base, the margin entire and revolnte; texture 

 thick and leathery; no venation apparent except tlio midrib on the under 

 side; branches of the bi- or tri furcate inflorescence subtended by opposite or 

 whorled loaves toward the extremities reduced, and there surpassed by tlip in- 

 volucre-bearing pedicels; pedicels i inch long, erect; involucral cup as broad 



Tlio auljjoiiietl disposition of those forms is snggosteil.

a. Crests 2, the alternate ones reduced each to a ha.'ial tubercle. 



1. Branching diffusely from the base: F. gracilis Mm\. 



2. Larger, K-.cre erect, loss branchhig : P. gracilis Moq., var. Floridana. 



aa. Crests 5, the alternate ones each of J to 3 sliiirp spines: F. gracilis IMoq., rar. Drummondii. 

 II. Alatce. Creste in the form of entire or b.arely crenulate wiiiga : F. interrupta, tomentosa, alata. 



I am not prepared to differentiaie those last three species. With more material th.an is at present 

 available they may be found reducible to two, or one, good species. Certainly they look puzzlingly 

 Alike, so far as the present material shows.
